Topall "whom it concern:

Be it' zen of thexUnited States, residing at New Uhn, in the county of, Brown and State of Minnesota', have invented certain new angl useful Improvements in lin/proved Transfer Mechanism for Carrier`Systenis; and vI do hereby declare the following to. be a full, clear,'a n`d exact description of theinvention, such as will enable others skilled in the art to whichA it-appertains to inakeand use thesame.l Y, Y.

My invention has forits' object toprovide an improved transfer mechanism for carrier systems, and to this end, it consists of the vI'1ovel'devices and combinations of devices hereinafter described and defined 'in' the claims.

This improved transfer Fmechanism is adapted for use in connection with carrier systems wl'ierein there is a main orpriniarv carrier and one or niore'brai'ichor secondary carriers arranged at an approximately right angle thereto; and especially, said transfer mechanism is vadapted for use where tli-e carriers above noted involve laterally spaced endless `carrier belts or cables andcoperating, guiding and driving wheels.

Carrier systems of this character are vnow in general usev for a great4 many Ydifferent For instance, they. are found very serviceable. .in brick yards to convey pallet boards loaded with bricks' from the press along the main or primary carrier to one or the other of several branch or vond-ary carriers, by which Ilatter such loaded palletboards are carried to suitable places` of deposit.

My improved transfer mechanism is arranged to operate automatically, to pick up in succession the loaded pallet boards (or other parcels) from the. main or primary carrier, and to deposit the same smoothly and accurately upon the branch or secondary carrier.

In the accompanying drawings which illustrate the invent-ion, like characters indicate like ,parts throughout Athe several views. Referring to the drawings: Figure 1 is a plan view illustrating my improved transfer mechanism operatively applied to a carrier system such as above indicated,

some parts thereof being broken away and some parts being shown in section. Fig. 2 1s a vertical section taken o-n the line Specification of LettersiPatent lApplication filed September 16, 1908. Serial No. 458,318.

Flig. l1 is a detailin section taken approximately on the line ai as of Fig. 2; Fig 12 is a diagrammatic plan view illustrating the arrangement of a carrier systeni of the general character above indicated, wherein several brauch 'orsecondary carriers are employed in connection with a main' or primary carrier.

Of the parts 'of the carrier system'proper, the numeral l'illustrates an elongated frame work of the so-called main carrier and the numeral 2 indicates the laterally spaced endless carrier belts which as shown, are in the form of cables, and are arranged to run over 'laterally spaced pairs of grooved Wheels 3 and i secured respectively to shafts-5 and 6 journaled in the sides of the frame work 1. 4The branch or secondary carriers, each comprises a pair of laterally spaced endles belts or cables 7 arranged to i'uii over grooved wheels Sand over other grooved wheels-not shown. All of the wheels 8 are secured on va long shaft 9 that extends parallel to the main carrier at one side thereof, is j0urnaled in suitable bearings 10 and 11, and is geared to the shaft 5 by a pair of niiter gears 12. On the said shaft 9 is a pulley-13 over which the power driven belt. 14 runs to impart motion to two shafts 5 and 9, and hence to the main and branch carriers.

For picking the pallet board or other parcel up 01T from the belts 2 of the niain cai'- rier, I provide a so-called parcel lifter which is mounted on a small rectan ular supple! mental frame, preferably ma e up of side framesl that are spaced. apart and tied together by pipe sections/.or sleeves 16. This supplemental frameI is detachably secured to` 69 loosely mounted on shaft 9, and is provided bearing plates 17 secured on the sides lof the main carrier framel.- This detachable-con nection between tle` said supplemental frame;j plates 17, is conven-A4 and the said bearin iently made by ro s 18 that arev passed through sleeves 16 andthrough Vthe .said bearing plates 15 and' 17 .f A pair of parallelf.

rock Shafts -19 and '20 are journaled upon ends in the sides 15 of the-detachable sup'- plemental frame, and these rock shafts are, provided with laterally spaced pairs of parallel'arms 21- that are lconnected by parallel lift-ing bars 22. VAlso as shown, said rock:

, tions of the belts 2, so that the parcel or loaded pallet board-will not sag the belts at the point where it is--carried above the lift# l ing bearings 22. Mounted in depending portions l5a of the bearing plates 15 of the detachable supplemental Iframe, is a third rock shaft '26, lto which is secured a -pair of laterally spaced trip arms 27, the free upper ends of which extend above the upper por? tions of the belts`2 in a position to be engaged by the pall'et board 0 1' other parcel. 1 The said pallet board in the drawings is indicated by the'letter a, and thebricks contained thereon are indicated by the let-ter b. To one of the trip arms 27, a coiled spring 28 anda trip rod 29 are attached at one en'd. The other end of said spring is loosely attached to the rock shaft 19, and the other end of said'trip rod 29 is connected to one arm of the bell crank 30 that is intermediately ypivoted to ,a bearing 31, secured on one of the fixed sleeves 16 of the detachable supplemental frame.

Nearly transversely opposite to the so-- called parcel lifting device above described, thelong shaft 9 is provided with fixed longitudinally spaced collars 32, and -between these collars, located adjacent thereto, said shaft is provided with loose bearing Asleeves 33, see Figs. 1, 5 and 6, that are grooved at their sides and tops so as to receive and detachably hold U shaped orbifurcated bearing 'heads 34 of a detachable bearing yoke The intermediate portion of this yoke hasa bearing 3'6,in which is journaled the hub of .the miter'gear 37 that meshes with a miter gear 38 loosely journaled on the shaft 9. `Atits extended end, the hub with the gear 37, carries a crank arm 39.

Between -the hub of the. g'ear 38and the adjacent b earing sleeve 33, thecam hub 40 is with a radially projecting arm 41 and with a lateral projecting segmental cam 42, which ilatter, at its highest point, terminates abruptly, as best shown in Figs. 5 and 8, the hub of the said gear 38 being recessedto aiord a clearance for the said cam 42.- As

working position, and permitting the latter to be Vlifted from working position when it is desired to detach the bearing yoke 35 and parts mounted thereon. 'The said' bearing yoke 35 is provided with a depending pedestal 43, which is made up of twooverlapped sections rigidly but detachably connected by a bolt and slot connection 44, shown in Fig. 2. The lower end of this pedestal 43 is-"detachably-connected by a pin 45 to a bearing46 on the ioor or ground sup ort.

The .beveled gear 38 is provide with clutch teeth that engage with similar clutch teeth 47 formed on one end of a clutch sleeve 48, whichA latter is slidably mounted onlthe shaft 9, but caused to rotate -therewithfby means of va key 49. A light coiled spring 50 on shaft 9 is compressed between the clutch sleeve 48 and the adjacent bearing sleeve and exerts a force which tends to engage the clutch teeth of said sleeve 48 and gear 38. A clutch releasing pin l51 is slidably mounted in the hub of the gear 38, one end in position to be engaged 'by the segmental cam 42 of the cam hub, and With its other end in position to engage the end of the clutch sleeve 48 inward of its clutch teeth 4.7, as best shown in Figs. 5,\74 and 8. A rod 52 is connected at one end to the above crank 30, and at its other end, is detachably connected by a pin 53 to the arm 41 of the cam hub 40.

Y Ri idly secured .to the' Hoor adjacent .to the shaft 9, and about transversely opposite `to the central portions of the lifting bearings 22, is a pedestal 54, to the upper end portion of which, is'rigidly secured aU shaped coupling yoke The downturned end of a detachable bearing bracket 56 is engaged be tween the yoke 55 and, the pedestal 54, and is securely held thereby by means of friction and gravity.

-Rotatively mounted in the vdetachable bearingr 56 and loosely seated at its lower endinthe base of the pedestal 54, is an upright oscillatory shaft or stem 57, thcupper end of which, as sho'wn, 'is tu`rncd into a horizontal position to atl'ord a carrying arm 58. Below the -bearing 56', the shaft 57 is provided with a radially projecting hub 59, to which a short headed -arm 60 is swiveled. The crank rod 61 is pivotally connected at one end to lthe crank 39 of the gear 37, and at its other end, it has a downturned stem and is pivot` ally mounted in the head of the short swiveled arm 60 of the vertical rock shaft- 57.

This crank rod 6l is preferablymade of two provided with a laterally projecting cam pin y 63 preferably equipped lWithfthe roller,

which under upward movement of the crank a detachable portion of the said shaft 19. A*

coiled spring 66 on the .shaft 65 reacts against the 'bearing 35a and against the hub of the arm 64, and yieidingly holds the said 'shaft 65 coupled to the rock shaft 19.

A lever like parcel transferring frame. 67

shown as provided with a bifurcated outer end portion,.is swiveled Vor rotatively inou'nted on a horizontal projecting portion 58 of the. vertical rock sha ftor stem 5l. Tothe ilrner end portion of this transferring frame 67, is secured a segmental cam 68 t-hat extends concentric to the axis of the vertical rock shaft 57 and rests upon a supportinaa roller 69, shown as journaled to 'a small bracket 70, (see Figs. 1 t and 11). .The mental cam 68 hasv an abruptly inclined intermediate portion 68a., and furthermore, the free end portion thereof, is' slightly inclined for an important'purpose -which Will appear in the description of the operation. .I

Operation: The directions in which the endless" carrier belts 2 and 7 are driven, are indicated by arrows marked adjacent thereto on Fig. 1. When the loaded pallet board is placed on the carrier belt 2,' it will be carl ried toward the left iii-respect to Figi. 1, and

toward the right in respect to Figf, until it. strikes the upper ends of the tripping arms 27, whereupon this engagen'icnt, will,v

through the rods 29 and 52, and an interme diate bell crank 30, rock the cam hub et() far enough to cause the shoulderedextremity of the cam 4:2, to be out of engagement with the pin 5l. thereby permitting the spring 5() to move Athe constantly drivg-n clutch sleeve 4S toward the left in respect to Figs. 1 and 5.' thus coupling the initer gear 38 to -the driving shaftfl. This causes thedriving shaft Sl. through the initer gears 37 and 38, to rotate the crank 39. The upward movement of the .said crank 3S) causes the rollei (lto4 engage the arm 64 and thereby rock the sectional shaft 19-(35, and thus to raisethe tivo lifting bars 22 and cause'the latter to pick up and elevate the "pallet board. This same movementof the crank 39, acting through the connectingrod 61, carries the transferring frame 67 from its normal position indicated by. the full lines in Fig. -1, into the receiving position indicated by the dotted linesI in Fig. 1. When the said transferring frame thusI moved from itsnormal into its receiving position, the roller 69, acting tirst on the cam portion 68, and then on the tail portion of the said cam, raises the free end of thel said transferring frame and guides the same slightly under the loaded allet board, which at a time when the sait transferring frame reaches its said dot- `ted line receiving position, is 'elevated or held upward by the lifting bars 22, which then stand in a positionindicated bythe dotted., lines iii-Fig. 3. lVhile the lifting bars 22 eind the transferring frame are in the relative position above stated', the crank 39 app-roaches the limit of its movement to- Wardtlie -right in respect to Fig. 1, and toward the left in respect to Fig. 2, and the roller 63 then passes ont of engagement with the free end of the arm 64 and thus permits the bars 22 to drop, leaving the lower palle'tboard deposited upon the transferring frame 67. Q v

rflic return movement of the 'lowerhalf stroke of the crank 39, serves to return the Atransferring frame 67 to its normal 'Josition over the receiving position of `the elts 7;

4and just before the said transferring frame the free end of the said transferring frame to lower' and thereby deposit the lower palletboard on the said belt 7 in a position at a right. angle' thereto. .l

ll-'hen the crank 3S) completes its full stroke., the pin 5.1 reaches the highest point on the cam 42 of the cam hub 40, (which `latter assumed its'y normal position when the lifting bars 22 carried thepallet boa-rd upward out of engagement with the free ends ofl the .spring retracted tripping arms 2'?) andv thereby forces the clutch sleeve out of engagement .with the clutch teeth of the gear 3S. This of course, disconnects the gear 3S fron'rthe driving shaft 9,' and leaves all of the parts of the transferring` mechanism in their normal positions. By the pin 51.y cam 42. and clutch members, it will be seen that they constitute a one-revolution clutch mechanism 'for throwing the crank St) into and cut of action.

By reference to Fig. 12, itfWill benotod `that severa-l branch or secondary carriers aref emplcyed in connection with the main or pririijary carrier. llllicn it is desired to ion shift the transferring mechanism from the 4], all of that part of the transfer niechanism which is applied to the side frames 1, and of the main carrier, mayl be detached therefronnand when brought into another proper position, the location may be again coupled thereto by reapplying the said. rods 18 and insenting the said pin 53 in the arm 41, since the collars `32,- grooved bearing sleeves v50, gear 38' and clutch sleeve 48, are

"permanently applied on the driving -shaft 9 adjacent to each of the several branch or secondary carrlers.

The bearing yoke 35, together with the"4 gear 37, the crank 39, the crank rod 61, the vertical rock shafti 57, the transferring frame 67, and connected parts, may be 'detached and removed, this operation' sim;- ply requirin that the pin 4 5 in the floor bearing 46, e first removed, and then the bifurcated lheads 34 be lifted from the grooved bearing sleeves 33, and the bearing 5 6 be liftedutof the yoke 55.

. T o rovide for the ap lication of the detachab e parts justnote the floor bearing 46and'pedestal 54 with'yoke 55, should also,

' of course, be provided at the several places y where they are to be applied for copera tion with -theseveral branch carriers.= The lpedestal 43 ismade vertically /adjustable so that it may be adapted to irregularities in l'the floor.- ,The crank rod .61 is made adjustable so that the movements of the transe'rring frame 67 may beproperly regulated -in respect-to the lifting movements of the 30 lifting-bars 22. i

vFrom lwhat has above been said, it is thought to be eviden-t, that a highly efficient transfer mechanism' for .carrier systems of the general character above stated, has been'l provided. By making most of the parts of the transferrlng mechanism detachable and capable of operative'connection'at different points along the main carrier, a very great saving in costis effected. The efficiency -of the mechanism above described, has been demonstrated in actual practice.
